Answer:
Explanation:
given cells at incubation = 2 million (2 x 10^6) Staph
cells at the start of incubation = 200 Staph
Total time =6hrs = 360minutes
Recalling that Number of generations = Log(cells at incubation) - Log (cells at the start of incubation)/0.301
- Number of generations = Log 2000000 - log 200 /0.301
= 20.93 generations.
- hence generation time = total time/number of generations
= 360/20.93 = 17.20minutes
as said, that the apple pie is left after 2hrs, it implies 8hrs (480minutes) will be the new total time; number of generations = total time / generation time
= 480/17.20minutes = 27.90 generations
- hence total number of bacteria after 8hrs = 2^n generations x initial number of bacteria
= 2^27.90 x 200 staph = 5.009 x 10^10 bacteria

Answer: The correct answer to the question is option C
BECAUSE YOU HAVE HAD ONE CHILD WITH TAY-SACHS,YOU MUST EACH CARRY THE ALLELE.ANY CHILD YOU HAVE HAS A 25% CHANCE OF HAVING THE DISEASE.
Explanation: Tay- Sachs is a rare disorder that is inherited,it is characterised by a progressive destruction of the nerves of the brain and spinal cord.its onset is from around 6months of life to around 4-5years of age when the child affected eventually dies.
A Child that have Tay-Sachs experiences problem with coordination,muscle contraction, must stiffness and weakness.there is also difficulty is speaking, swallowing, wasting(uncontrolled weightloss), hearing loss,seizure, and vision loss.
Since the parents of the child in the question claims they don't have Tay- Sachs and no one in the family has it but they came down with a child having Tay-Sachs and one of the major factors to Tay-Sachs as stated above is heredity,the main point to counsel the couples on is that because they have had one child with Tay-Sachs,they most each carry the allele which is obviously recessive so any child they had have has 25% chance of having the disease.
Answer:
S phase
Explanation:
S phase is the second phase of interphase (longest phase where cell grows and replicates it's DNA and does it function. It is broken up into smaller sub phases). S phase is the synthesis phase. During this phase chromosomes are replicated ( The DNA is copied).
